Answer by liberalthinktankProbably not a whole lot. Go to one of those training schools listed on your yellow pages or google plumbing schools in your area. Some may be able to make you a loan and you can pay it back once you start rolling in the cash. You could make a good living off of a plumbing career, as you are you’re own boss and can charge out the yin yang! Oh, hope you have the right pants for your new profession!!! Ha, ha just had to throw that in!
